Educational Objectives:

Upon completion of this workshop, participants should be able to:
  • Recognize MR safety concerns involving static magnetic fields, time-varying gradients, and radio-frequency fields;
  • Recommend methods to minimize patient heating from surface coils and other conductors;
  • Implement procedures to minimize patient and operator safety concerns;
  • Compare various national and international safety standards and limits;
  • Identify potential safety flaws in their current clinical scanning procedures;
  • Evaluate safety aspects of new MR technologies currently under development.
